#157556 - Which example? Responding to: ???'s previous message |
I produced HID device based on Atmel keyboard enumeration example...
I found out that the program freezes in the section where the device descriptor is being sent. The bug is still in the same section. a) Which Atmel example do you use? Can you show the URL to the example? b) Is the pull-up resistor to the USB D+ line (1.5k) is connected to Vref pin of the AT89c5131 at the other end? Tsuneo |
